Description
Black Hole is a towering humanoid figure with obsidian-black skin and a gaping facial cavity opening into fourth-dimensional space. His imposing 201 cm, 420 kg frame bears crimson markings: a star above the dimensional void, initials "B" and "H" etched across his pectorals, complemented by red combat shorts, gloves, boots, and a flowing cape. He wields shadow manipulation, space-time distortion, and gravitational absorption through his cranial portal to a crushing alternate dimension—a power countered only when damage to his form fractures the dimension’s structure, enabling captive escapes.

Once among the Seven Devil Chojin, his exile followed the slaughter of 100 Justice Chojin. Childhood torment by the Bermuda III ceased when cousin Pentagon aided him, forging the 4D Killer Combo tag team. Their domination over former bullies inspired local youth leadership, though their paths later diverged: Black Hole embraced Devil Chojin ideals of power-enforced order, while Pentagon championed justice. Despite opposing philosophies, their unbroken trust led to recurring alliances to claim the title of ultimate tag team.

During the Seven Devil Chojin Arc, he battled Kinnikuman in a Solar House Deathmatch, deploying shadow duplicates and dimensional traps. Defeat nearly cost him execution until Pentagon’s plea spared his life. His spirit later haunted adversaries via the Blood Bind technique until Brocken Jr. severed the link. Resurrected for the Universal Chojin Tag Tournament, he and Pentagon honed aerial tactics and dimension-shifting positional swaps, though victory eluded them.

A non-canon resurrection as "New Black Hole" by Hydra King saw upgraded abilities deployed to abduct Robin Mask, thwarted by Ramenman.

In the Perfect Origin Arc, he allied with former enemies against the Perfect Chojin, clashing with Dalmatiman and Jack Chi. Innovating mid-battle fusion techniques with Pentagon, he executed their collaborative "Jack Chi" finisher upon his partner’s urging, blending dimensional tactics with shadow assaults against enhanced foes.

Masking brutality beneath courteous dialogue, he strategically misled opponents while pursuing invincibility through raw power. Alliances with both Devil and Justice factions served this singular aim, yet his loyalty to Pentagon transcended ideological divides, anchoring their relentless quest for supremacy.
